I'm basing all this off of the personal preference of an ssd only system, no mechanical hard drive, should at least have a 250gb SSD.
I would ditch the SSD for spinning rust and put that money towards a better cpu. An SSD will help a ton, but I think a better processor would be the better value. A cheap 250gb ssd is $80, you can pick up a WD Cavier Green 1TB for $50. Apply that $30 savings towards a better processor. The R3 1200 goes on sale for $100-105 semi often, you have 2 months to watch for a sale.
I know it's more money than what you anticipated, but I think the changes would really be beneficial. Add an SSD down the road.
Here's a video with gaming benchmarks with the x4 950, R3 1200, and G4600. Both AMD chips have stock and oc'd results. The R3 1200 handily stomps the x4 950, a lot of cases it's double the fps.
